The NI Greens are here too, as @greenpartyni

Together with the Scottish Greens, that's two of the four UK nations covered.

A grid-tied solar PV inverter isn't like a gas generator. It follows the grid waveform and will cut out within one cycle if the grid is lost. Unplugging the inverter, the plug is dead before the pins are exposed to be touched.

At 230V, 800W (the German limit for plugin solar) is ~3.5A. The German electrical regulator has deemed that a typical 16A power circuit wired in 1.5 sq.mm. cable will still be safe with 3.5A of current fed from the "wrong end".
